BTWhat forecasters said that day
The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Detroit, MI wrote its last area forecast discussion before this river flood warning went out at Sep 22, 3:47 AM EDT, 1 hour earlier.
Area forecast discussion, Sep 22, 3:47 AM EDT, 1 hour before
Area Forecast Discussion
National Weather Service Detroit/Pontiac MI
347 AM EDT Wed Sep 22 2021
.DISCUSSION...
A Flood Watch remains in effect for most of Southeastern Michigan
through Wednesday night.
Larger breaks in rain activity have occurred overnight as the main
forcing from the cold front shifted to the east and instability
quickly decreased with as cooler air filtered into the region. This
cooler air will limit potential instability and prevent any
convective development today. Rain coverage is expected to increase
again this morning as the upper low over the mid-Mississippi valley
swings into the Ohio valley placing the left exit of the jet streak
over southern SE MI. Upper level support spurs the formation over
surface low pressure along last evening's cold front across Ohio. SE
MI remains under this upper level divergence through the day today
as the polar jet retracts northward over northern Ontario pinching
off the upper low from the mean flow. Model tracks continue to take
the associated surface low nearly due north across Ohio into either
far eastern SE MI or western Ontario. The deformation axis stays
over the region given this track and increases in strength this
afternoon and evening coincident with the surface low strengthening
as main PVA swings into western OH. As a result, another couple
inches of rain will be possible through this evening. Northerly
winds increase from the tightening pressure gradient daytime today
with gusts this afternoon into early tonight peaking around 30-
35mph.
The rapid maturation of the surface leads to occlusion by early
tonight allowing drier air to wrap into the circulation,
particularly in the mid-levels. Drier mid-levels supports lessening
rainfall rates and more frequent breaks in activity tonight into
Thursday morning. Lighter more scattered shower activity does still
linger through the day Thursday however from the trowal drifting
over the area as the low retrogrades. The upper trough also moves
directly overhead daytime Thursday providing continued upper level
support for shower activity.
Upper level low quickly slides north Thursday night into Friday as
its reabsorbed into the mean flow due to a new upper wave over
Manitoba pulling the jet further south. Height rises briefly work
into SE MI daytime Friday in between these two upper waves bringing
back clearer skies and near-average high temperatures.
Aforementioned Manitoba upper trough digs south into western Great
Lakes Saturday allowing a surface low to form over the northern
Great Lakes. This low drags a cold front across southern MI Saturday
afternoon bringing shower chances back to SE MI. High pressure then
builds into the area from the south Sunday into Monday drying the
region out.
&&
.MARINE...
A cold front has cleared just east of the central Great Lakes this
morning, but will remain stalled in the vicinity promoting numerous
showers and perhaps a few embedded thunderstorms. Low pressure lifts
north along the boundary and lingers through Thursday morning
resulting in a constricted pressure gradient. Expect sustained winds
to approach or exceed gale force while stronger winds aloft broadly
mix down gusts to gales. Portions of central Lake Huron may
experience brief strong gales in excess of 42 knots. A Gale Warning
remains in effect from 9 AM EDT today through 8 AM EDT Thursday for
all DTX marine zones. The long-duration enhanced N/NE flow will also
produce occasional waves near 20 feet late tonight for parts of the
southern half of Lake Huron. Winds drop-off mid-morning Thursday,
but resultant wave energy may warrant a back-end Small Craft
Advisory for the southern Huron nearshores. Winds remain modest into
the weekend.
&&
.PREV DISCUSSION...
Issued at 1250 AM EDT Wed Sep 22 2021
AVIATION...
Mixed MVFR/IFR continues to solidify from PTK southward late tonight
as the cold front stalls from southern Ontario into central Ohio.
The north fringe of ceiling restriction hovers around FNT depending
on rain intensity while MVFR becomes more dependent on wind
direction at MBS. NE flow off Lake Huron/Saginaw Bay reinforces at
least MVFR from there down to FNT while IFR holds for longer
duration south of PTK, closer to the front and where heavy rainfall
sets up again by mid to late morning through afternoon. The deepening
surface low occludes in central OH leading to strong gradient wind
in SE MI. Northerly gusts near 30 knots combine with modest boundary
layer growth to push ceiling up into low end MVFR mid afternoon into
Wednesday evening with VFR developing toward MBS.
For DTW... Ceiling settles into IFR during the late night with the
cold front stalling nearby to the south. A decrease in rain coverage
and intensity during the late night reintensifies during the morning
to add IFR visibility for much of the day. North wind gusting near
30 knots ensures the need for north traffic flow.
DTW THRESHOLD PROBABILITIES...
* High for ceiling 5000 feet or less late tonight into Wednesday
evening.
